The Schedule referred to in these Letters Patent and making part of the same To all whom, 'it may concern Be it known. that I CHRISTOPHER OsrnANDna, of

Lodi, in the county of Columbia, and State of Wisconsin, have invented certain new and useful Improvements in Farm-Gates; and I do hereby declare that the. followingr is a full, clear, and exact description thereof', reference being had to` the accompanying drawings, making part of this specification, and to the letters oi' reference marked thereon, like letters indicating like parts wherever they occur.

To enable others skilled in the art toeonstruct and use -my invention, I will proceed to describe it.

My invention relates to gates; and

It consists in certain improvements upon that class ot" darm-gates which is opened by sliding th'ein back a portion of their length, and then swinging them around.

In the drawiug- Figure 1 is a side elevation of my gate, closed, and

Figure 2 is a top plan view of the same, open, a portion of the top rail being broken away to show other parts more clearly, andthe position ot' the gatewhen closed, shown by dotted lines. v

A A are the gate-posts, the former having secured to it 'a projecting arm or bracket, a, provided at its outer end with a vertical hole.

Bis a metallic swivelling head, mounted ou and having a stem fitting into the hole in arm a. l

This head B, I cast of metal,`iu a single. piece, and ofthe form shown, and place in it two rollers, e c, whose journals have bearings between the arms l1 b b of the walls of the head.

In the head, below thevrollers crc, I make openings down through, so that snow, dirt, water, Src., gettingV into it, will escape through these openings, instead ot mpeding the action oi' the rollers, especiallyin the winter-season.

C is the gate, having its front barj extended below the bottom rail, and having pivoted in its lower end a roller, E, as shown in fig. 1.

This gate O, I place with the hack end of its top mil d resting in head B upon Vthe rollers c c, the arms` b l) serving to guide the rail, and keep it upon the rollers, as shown in figs. 1 and 2.

When thus arranged, the head B supports the rear, and the roller E the front end of the gate, at the proper height, and oft' from the ground.

To close the gate, it is only necessary to apply sui'- cient power to slide the gate upto post A', and not,

as with the ordinary gates, to support the fi'ont end by hand. v I

To open the gate, itis slid back until it balancesupon the rollers c c, and .the roller E rises from the ground, and it is then turned around, upon the swivelled head, to the position shown in iig. 2.

To prevent accidental displacement o f lthegate from the head l, I drive into the post A, above the top rail d, a pin or peg, It, and also'drive into the l earth, outside ofthe gate, opposite the. corner of post A, a stake, e, as shown in iigs. 1 and 2.

To aidiu opening the gate quickly, I secure on the gate the vertical bar m, in such position that when the gate has run back the proper distance to balance, the har will strike against the head B, and prevent further longitudinall movement. ot the gate, which may be run hack quickly, and not be liable'to pass the balancing point, aswould occur were it not for this har or strip.

F is a catch, passing lengthwise through the front ot' the gate, and pivoted at o, the inner end being made to overbalance the outer, and the outer end having formed on its upperside a bevelled catch or head, g.

To 'secure the gate by this catch, it is only necessary to close it, when the outer end of the catch enters a mortise made through post A for the purpose, and its head g, projecting through, engages over the outer edge of said mortise, and thus prevents the gate from being drawn back.

The gate is released by lifting the -inner end of catch or level' F, which disengages the' head g.

h. is an arm or block, secured to the front end ot' thegate, immediately below the latch F, and which, whnthe gate is closed, enters the mortise with the catch, thus relieving it from lateral strain, which would canse it to bind in the mortise, and render its disengagement difficult.

This gate is strong, cheap.'and elicient, can be operated by a small child, and isV not liable to injury by snow or ice.

Having thusdescribed my invention,

The gate C, hung on the two rollersl c c, mounted in a swivelled case., B, and provided with rollerE and pivoted latch F, to engage in post Ai, all constructed and arranged as herein described.
